Alrighty, gonna buy Coralis tomorrow, after work. Price is like 15 bucks, so I can cover that without any problem. I'll see if I can get it set up as a mobile theme first, then mess around with the colors later.

Current best-practice design theory is that content should go on the left and other information should go on the right. Avatars on the right makes sense from that perspective. And I can usually tell who's talking just by catching the avatar out of the corner of my eye.

That said, I think username should be above avatar, not below it.

Not that anyone should take any of my ruminations as a vote; I'm probably just going to revert back to SubSilver anyway because I am boring.

index.php and viewforum.php have horizontal scrollbars for me, at 1050 pixels wide (on Firefox, if it matters). The horizontal stretching does not appear to be caused by anything, as the only thing that's that wide are the forum and thread listings, which are full of empty space.
